Battle of Amja
The battle of Amja was the first battle fought between the Kanem–Bornu Empire and the warlord Rabih az-Zubayr, who invaded the empire in 1893. The battle was fought at the end of May 1893 near Amja, on the southeastern Bornu frontier.
Background
In the summer of 1893, the Sudanese warlord Rabih az-Zubayr, moved his army into Bornu, having already conducted extensive campaigns in surrounding territories.' The ruler of Bornu, Ashimi, delegated leadership to stop the invasion to the general Momman Tahr, perhaps hoping that Tahr would be defeated so that he would be eliminated as a political rival.' Rabih awaited the response from the Kanem–Bornu Empire at Amja, on the Bornu frontier.Army compositions
Rabih az-Zubayr's army numbered about 3,000 men, half of whom were armed with rifles and muskets. The force commanded by Momman Tahr was significantly larger and consisted mostly of cavalry. Some sources claim that Tahr commanded as many as 30,000 men, though this might be an exaggeration.''''''Battle
Rabih's forces were on a raised fossil dune, fronted by clay that had been made sticky after recent rain. Rabih further positioned his army so that his right flank was protected by a swamp.'Sources about the battle claim that Tahr made a tactical blunder, leading a frontal charge through the swamp in an attempt to catch Rabih by surprise.' During this charge, a large segment of cavalry are said to have become stuck in the swamp and then shot down by Rabih's riflemen.' Lavers doubted this account since Tahr was an experienced general, who along with several of his officers would have had experience with the region. Lavers proposed that the battle took place on the onset of the wet season and that the horses instead became stuck in wet clay.
After the stuck cavalry was decimated, the rest of the Kanem–Bornu army fled.' Momman Tahr and two leading kachellas were captured in the battle and were executed by Rabih.''''''
